rzmq is an R binding for ZMQ (http://www.zeromq.org/).
rzmq is a message queue for serialized R objects.
- rzmq implements most the standard socket pairs that ZMQ offers.
- ZMQ devices are not implemented yet, nor is zmq_poll.
- Look for more features shortly.
A minimal example of remote execution.
execute this R script on the remote server:
#!/usr/bin/env Rscript
library(rzmq)
context = init.context()
socket = init.socket(context,"ZMQ_REP")
bind.socket(socket,"tcp://*:5555")
while(1) {
msg = receive.socket(socket);
fun <- msg$fun
args <- msg$args
print(args)
ans <- do.call(fun,args)
send.socket(socket,ans);
}and execute this bit locally:
library(rzmq)
remote.exec <- function(socket,fun,...) {
send.socket(socket,data=list(fun=fun,args=list(...)))
receive.socket(socket)
}
substitute(expr)
context = init.context()
socket = init.socket(context,"ZMQ_REQ")
connect.socket(socket,"tcp://localhost:5555")
ans <- remote.exec(socket,sqrt,10000)
